Report Information - Report Title: Synthetic Rubber Weekly Report [1] - Report Date: February 01, 2026 [1] - Analyst: Yang Honghan [1] Industry Investment Rating - Not provided in the given content Core Viewpoints - The synthetic rubber market is expected to experience a high-level decline in the short term. This is due to the reduction of geopolitical conflict probability and weakening macro sentiment, as well as the approaching boundary of some valuation indicators and the increasing negative feedback expectation [3][4]. - The butadiene market has limited short-term drivers and is expected to decline in the short term but has support in the medium term. The overall domestic butadiene fundamentals are balanced [5]. Summary by Directory Synthetic Rubber Supply - During the cycle, the high-cis butadiene rubber unit of Maoming Petrochemical restarted, and the load of individual butadiene rubber units in North China decreased slightly. The total capacity utilization rate only fluctuated slightly. The output of high-cis butadiene rubber in this cycle was 30,700 tons, an increase of 104 tons compared to the previous cycle, with a month-on-month increase of 0.34%. The capacity utilization rate was 76.38%, a month-on-month increase of 0.27 percentage points [4]. - There is no news of new unit restart or shutdown for maintenance in the next cycle, but the load of private butadiene rubber units still needs to be carefully observed [4]. Demand - In terms of rigid demand, some semi-steel tire sample enterprises were supported by foreign trade orders during the cycle, and the unit production schedule increased slightly, which supported the capacity utilization rate of semi-steel tire sample enterprises. The shipment of all-steel tires was dull, and some enterprises still had production control, dragging the capacity utilization rate down slightly. It is expected that the capacity utilization rate of tire sample enterprises will decline in the next cycle [4]. - In terms of substitution demand, the spread between the NR-BR main contracts has turned from positive to negative, and it is expected that the substitution demand for synthetic rubber will gradually weaken [4]. Inventory - As of January 28, 2026, the inventory of domestic butadiene rubber sample enterprises was 34,400 tons, a decrease of 1,000 tons compared to the previous cycle, with a month-on-month decrease of 2.74%. The price of butadiene, the raw material, increased unexpectedly this cycle, significantly driving up the butadiene rubber market. The low-price negotiation center shifted significantly upward, but the buying follow-up was slow. At the same time, butadiene rubber production was still significantly in the red, and some private enterprises in North China reduced their loads to varying degrees. The inventory of sample production enterprises decreased, and the inventory of sample trading enterprises increased slightly overall [4]. Valuation - The current static valuation range of the butadiene rubber futures fundamentals is 12,500 - 13,200 yuan/ton. The speculation is relatively strong, and the upward valuation pressure is invalid. In terms of the downward valuation, the NR-BR spread has completely shrunk, and the spread's support for valuation has failed. The effective support level is the butadiene rubber cost line, and butadiene is expected to support the butadiene price from the cost side. The theoretical full cost of butadiene is estimated to be mainly based on the butadiene price * 1.02 + (auxiliary agents + labor) = 10,500 * 1.02 + 2,500 ≈ 13,200. In terms of the actual full cost, depending on the factory, the fixed cost ranges from 1,500 to 2,500 yuan/ton, so the minimum cost is about 12,500 yuan/ton (10,500 * 1.02 + 1,800) [4]. Strategy - Unilateral: After overbought, short at high levels according to the valuation; the upper pressure is 13,600 - 13,800 yuan/ton, and the lower support is 12,500 - 12,600 yuan/ton (supported by the NR-BR spread and butadiene cost) [4]. - Cross-variety: The NR-BR spread gradually enters a low-level shock, and it is recommended to pay attention to the position of expanding the spread in the future [4]. Butadiene Supply - In this cycle (20260123 - 0129), the estimated weekly output of Chinese butadiene industry sample enterprises was 113,500 tons, an increase of 2,900 tons compared to the previous cycle, with a month-on-month increase of 2.61%. During the week, the units of Nanjing Chengzhi, Sierbang, Yanshan Petrochemical, and Hainan Refining and Chemical remained shut down, and the units of Shanghai Petrochemical and Maoming Petrochemical restarted one after another. The output of Sinochem Quanzhou Petrochemical was relatively limited, and the weekly output increased month-on-month. Next week, it is expected that the weekly output of Chinese butadiene sample enterprises will be about 116,500 tons, a slight increase compared to this cycle. The units of Hainan Refining and Chemical and Sinochem Quanzhou Petrochemical may gradually resume production [5]. Demand - In terms of synthetic rubber, the operating rates of butadiene rubber and styrene-butadiene rubber will remain high in the medium term, and the demand for butadiene will remain at a high level year-on-year. In the short term, as the maintenance of butadiene units decreases, it is expected that the rigid demand for butadiene in synthetic rubber will remain at a high level [6]. - In terms of ABS, the inventory pressure is relatively large, and it is expected that the demand for butadiene will only maintain a constant level, with relatively limited incremental demand [6]. - In terms of SBS, the operating rate increased slightly, and the rigid demand for butadiene remained unchanged, with limited changes [6]. Inventory - In this cycle (20260122 - 0128), the domestic butadiene inventory increased, and the total inventory of samples increased by 11.25% compared to last week. Among them, the inventory of sample enterprises increased by 3.85% compared to last week. Some enterprises' inventory increased slightly due to the restart of sporadic units and market fluctuations. The inventory of sample ports increased by 17.39% compared to last week. Although the raw material inventory of downstream enterprises was normally digested and merchants expected a decrease in imports in February, there were imported ships arriving at the port during this cycle, which affected the phased increase in sample port inventory [6]. - According to the report on January 28, the latest inventory of butadiene in East China ports was about 40,500 tons, an increase of 6,000 tons compared to the previous cycle. Although the raw material inventory of downstream enterprises was normally digested and merchants expected a certain decrease in imports in February, there were imported ships arriving at the port during this cycle, which affected the phased increase in port inventory [6]. Viewpoint - The prices of butadiene in Asia and Europe are relatively strong. Overall, the domestic butadiene fundamentals are balanced. Butadiene will decline in the short term and has support in the medium term [5].
